MAINTENANCE & FAULT-FINDING
9.1. Cleaning
If there is any build up of deposit on the unit, it should be gently cleaned with a cloth,
moistened with soft detergent. Solvents should not be used, and care should be taken to
avoid scratching any surfaces. The unit must be allowed to defrost naturally after being
exposed to snow or icy conditions, do NOT attempt to remove ice or snow with a tool.
Do NOT remove black “rubber” transducer caps.

There are no moving parts or user-serviceable parts requiring routine maintenance.
